Product Description:

The MAC071C-1-NS-2-C/095-B-0/S001 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a motor for analogue drives that delivers closed-loop speed control to positioning tables, packaging stations, and other motion axes that still rely on analog velocity commands. By pairing the motor’s tachogenerator with legacy amplifiers, installers gain real-time speed feedback without adding digital encoders, and the absence of a blocking brake keeps the design suited for applications that already include external holding devices.

This model reaches a nominal speed of 3000 min⁻¹, so it can synchronize with drive shafts that require moderate high-speed rotation while maintaining the torque curve defined by its NS winding code. Heat generated at that speed is removed through axial surface cooling, and the internal blower operates on AC 230 V, eliminating the need for an external low-voltage fan supply. Mechanical alignment during mounting is aided by a centering diameter of 95 mm, which matches flange templates common to mid-frame servo gearboxes. Speed feedback is provided through a built-in device with tachofeedback, allowing the connected analog controller to measure shaft velocity directly as a proportional voltage.

The tachogenerator outputs 3 V/1000 min⁻¹, giving controllers a predictable reference over the motor’s operating range. Frame designation 071 defines the stator diameter, while winding code NS characterizes the coil resistance and inductance selected for 240 V class drives. Power enters the unit through a connector to side B, keeping cabling on the non-drive end so the opposite end can couple to pulleys or gear reducers. A C-length stack balances electromagnetic torque with rotor inertia, and the motor is supplied without a blocking brake so the machine builder can use mechanical clamps or the drive’s regenerative torque to hold position during power-off states.
